Map Sensor January 18, 2005, 08:57:55 AM Can I use a MAP Sensor from a Mass Air HO Engine for a Speed Density HO Conversion??? The MAP Sensor is off an HO Tbird with MASS air in a junkard. Thanks Quote Selected
Re: Map Sensor Reply #1 – January 18, 2005, 05:03:52 PM I have heard tha tthe only diffrence between the two is that the mass air dosent have the vacume tube that goes to it or somethign like htat. hopefully someone else will jump in here Quote Selected
Re: Map Sensor Reply #2 – January 18, 2005, 05:46:11 PM It is true you can use the map from a maf car for sd and vise versa but you may have a problem fitting a vac line on it.Otherwise the part #s are the same if you look into the aftermarket like i did just to verify.If the mass air car was a conversion or a stang grab all the mass air stuff(computer,maf and bracket,wiring connector and tubes from the TB) much more worth your time than the SD.

The cap on the vaccum port should just pull off, allowing the hose to fit.Is there a problem with your original MAP?? Don't let anybody tell you they are different, cause they are all the same... BAP, MAP, HO, SO, 3.8, 4cyl... no difference. Quote Selected
Re: Map Sensor Reply #4 – January 19, 2005, 08:12:04 AM Thanks guys, UPDATE: my HO conversion with ported upper an lower intake/TB is almost complete. Next to come are a set of E7TE heads ported/polished/decked/milled with 1.94/1.68 valves and a 3 angle valve job. THEN...the much needed paint job. I baught the car for 200.00 from my preacher. He left it in his backyard under a tree for 7years so it REALLY needs body work. I had to put a new tranny in it but it has been well worth 200 so far. Thanks Again! Quote Selected

The one I have on my '88 V8 Blue Max at this very moment raises the idle significantly over the rest of them. The others, they're all the same as far as idle quality. But this one is absolutely 100% different. You got me why....I have no clue, and normally I would agree with you. However, the proof is right under my hood. Quote Selected

Sometime when you have nothing better to do, "T" in a vac gage at the sensor and check the readings with different MAPs. I'm betting that one will be less than the others. Quote Selected
